How it works

Three steps, the same for every tool.

  1. 1

    Choose your file

    Select a PDF or image, or drag it onto the page. It opens inside your browser and is not uploaded to our server.

  2. 2

    Set your options

    Pick pages, order, size or style. Previews show the result before you create the file.

  3. 3

    Download the result

    A progress window runs to 100%, then the Download button appears. Closing the tab clears the working data.

Why people use mypdf.site

Private by design

Files are processed on your own device, so they are not sent to our servers.

No upload queues

The work starts when you click. Speed depends on your device and file size.

No sign-up

Open a tool and start. No account or installation is needed.

Works on phones

Touch-friendly layouts for phones and tablets as well as computers.

Your documents stay on your device

The tools run inside your browser, so contracts, IDs and statements are not uploaded to our server for processing. You can confirm this yourself in about a minute using your browser's developer tools.

Quick answers

Is mypdf.site completely free to use?

Yes. The tools are free to use, with no sign-up and no usage limits set by us. The site is supported by advertising and optional donations.

Are my documents uploaded to a server?

No. The tools process your files inside your own browser. The file is read into your device’s memory, changed there, and the result is saved back to your device. It is not sent to our servers.

How can I check that my files stay on my device?

Open your browser’s developer tools with F12, go to the Network tab, and then run a tool. You will not see your file being sent anywhere. The only extra download you may see is OCR language data the first time you use that feature.

What is the maximum file size?

We do not set a fixed limit. The practical limit is your device’s memory. Computers usually manage large documents, while phones are more comfortable with smaller ones. If a very large file is slow, work on fewer pages at a time.
